Flooding and power outages could hit Cumbria and parts of the North East as a storm sweeps across the UK.
The Met Office has issued a yellow thunderstorm warning for much of the country and said heavy rainfall could hit some areas.
The weather service said the full extent of the storm was unclear but there was a "slight chance" businesses and homes could lose power or suffer from flash flooding.
Heavy showers and thunder are expected until midnight.
The Met Office said all of Cumbria could be affected by the storm, as well as Darlington, Durham, Gateshead, Hartlepool, Middlesbrough, Newcastle, North and South Tyneside, Northumberland, Redcar and Cleveland, Stockton-on-Tees and Sunderland in the North East.
